audio range signal is expected. To boost the audio signal, set the Audio Max Level to the maximum value expected between 1
and 255. If there is a lot of noise then set the Audio Min Level to eliminate the noise.
22.4.13 Mixing between Pixel Mapping layers
The interaction of the different pixel mapping layers can be controlled using the Col Mix attribute in the colour page. The types
are
• Add
• Subtract
• Max
• Min
• Exclusive Or (EOR)
• Priority (higher layer numbers have priority)
• Priority > 0 (priority if level greater than 0)
• Masking
• Mask invert
• Blue key
• Green key
• Multiply
• No base
• Max with base
When a layer is set to “green key” then any green pixels in that layer pass through the media from the lower layers. Non-green
pixels play back the media on that layer. The mask must be pure green.
When a layer is set to “blue key” then any blue pixels in that layer pass through the media from the lower layers. Non-blue pixels
play back the media on that layer. The mask must be pure blue.
When any active Pixel Map layer is active (dimmer above 0%) then setting “no base” on that layer will make the Pixel Map effect
ignore any base level for the controlled channels instead of adding to the base level.
When any active Pixel Map layer is active (dimmer above 0%) then setting “max with base” on that layer will make MagicQ
perform a maximum of the Pixel Map effect and any base level for the controlled channels instead of adding to the base level.
22.4.14 Colour Mixing
The Colour Page of attributes allows the levels of the red, green and blue attributes to be set independently. The default values
are 128, 128, 128. Each colour can be boosted or cut.
The Colour Type attribute allows the overall colour to be adjusted including inverts, mapping of colours, black and white and
other colour effects.
22.4.15 Apply Type
Added new apply type to the Pixel Mapper of “use int” and “fit use int”. When these apply types are used the Pixel Mapper
applies to the intensity channel of the fixtures in the grid instead of to the RGB channels. If the fixtures in the grid have no
intensity channel then no pixel mapping is applied to the fixture. This is useful for example to use the pixelmapper on the
intensity channel of moving lights or on strobes.
